Blackmagic Media Player plugin enabled, but can't see Blackmagic Media Input or Output on Mac

I’m using an M1 Ultra Mac Studio and have a BM Ultrastudio Monitor 3G. I’ve tried enabling and disabling the plugins (and restarting in-between), as well as installing new and old versions of Unreal, but no matter what I try, the Blackmagic Media Inputs and Outputs just won’t show. Maybe it’s a Mac thing, but I thought I’d ask before I try installing Bootcamp.

Same problem on 2019 Mac Pro [Intel].

In another thread (in October), I was told that it should be available in the next few months on their main branch on GitHub, and I’m still waiting to use UE5 with my M4 chip.

The May 2025 and 5.6 preview is out, and there is still no Black media source. What’s the hold-u,p Team?
